For unix, combining just git and the built-in diff:

git show HEAD:path/to/file | diff -y - path/to/file

Of course, you can replace HEAD with any other git reference, and you probably want to add something like -W 170 to the diff command.

This assumes that you are just comparing your directory contents with a past commit. Comparing between two commits is more complex. If your shell is bash you can use "process substitution":

diff -y -W 170 <(git show REF1:path/to/file) <(git show REF2:path/to/file)

where REF1 and REF2 are git references – tags, branches or hashes.

If you are using an MVC framework with routes and actions:

$(document).ready(function () {
    $('a[href="' + this.location.pathname + '"]').parent().addClass('active');
});

As illustrated in this answer by Christian Landgren: https://stackoverflow.com/a/13375529/101662

1. Create two files in root folder (near by package.json) .env and .env.production
2. Add variables to theese files with prefix VUE_APP_ eg: VUE_APP_WHATEVERYOUWANT
3. serve uses .env and build uses .env.production
4. In your components (vue or js), use process.env.VUE_APP_WHATEVERYOUWANT to call value
5. Don't forget to restart serve if it is currently running
6. Clear browser cache

Be sure you are using vue-cli version 3 or above

I did not manage to find a way to do it directly.

Instead I imported the bak file into SQL Server 2008 Express, and then used MySQL Migration Toolkit.

Worked like a charm!

Two entries in an array can't share a key, you'll need to change the key for the duplicate

Remove all widths set using CSS and set white-space to nowrap like so:

.content-loader tr td {
    white-space: nowrap;
}

I would also remove the fixed width from the container (or add overflow-x: scroll to the container) if you want the fields to display in their entirety without it looking odd...

See more here: http://www.w3schools.com/cssref/pr_text_white-space.asp

When you are not sure of the number of rows, then you can do it this way:

followers_df.index = range(len(followers_df))

no you're just using it wrong. your is_number? has an argument. you called it without the argument

you should be doing is_number?(mystring)

I have this issue from time-to-time and often it's because the project wasn't marked as a java project. You can change this by going to the properties for the project > Project Facets > and selecting java. You may then need to properly configure that project, but this is probably part of the problem

In order to create a cronjob, follow these steps:

1. run this command : SET GLOBAL event_scheduler = ON;

2. If ERROR 1229 (HY000): Variable 'event_scheduler' is a GLOBAL variable and should be set with SET GLOBAL: mportant

It is possible to set the Event Scheduler to DISABLED only at server startup. If event_scheduler is ON or OFF, you cannot set it to DISABLED at runtime. Also, if the Event Scheduler is set to DISABLED at startup, you cannot change the value of event_scheduler at runtime.

To disable the event scheduler, use one of the following two methods:

1. As a command-line option when starting the server:

   --event-scheduler=DISABLED
   

2. In the server configuration file (my.cnf, or my.ini on Windows systems): include the line where it will be read by the server (for example, in a [mysqld] section):

   event_scheduler=DISABLED
   

   Read MySQL documentation for more information.

    DROP EVENT IF EXISTS EVENT_NAME;
     CREATE EVENT EVENT_NAME
    ON SCHEDULE EVERY 10 SECOND/minute/hour
    DO
    CALL PROCEDURE_NAME();
   

Perhaps use information_schema:

SELECT EXISTS(
    SELECT * 
    FROM information_schema.tables 
    WHERE 
      table_schema = 'company3' AND 
      table_name = 'tableincompany3schema'
);

1. Open design view
2. Right click to textArea
3. open surround with option
4. select "...JScrollPane".

Oracle has announced fix for Windows XP installation error

Oracle has decided to fix Windows XP installation. As of the JRE 8u25 release in 10/15/2014 the code of the installer has been changes so that installation on Windows XP is again possible.

However, this does not mean that Oracle is continuing to support Windows XP. They make no guarantee about current and future releases of JRE8 being compatible with Windows XP. It looks like it's a run at your own risk kind of thing.

See the Oracle blog post here.

You can get the latest JRE8 right off the Oracle downloads site.

The fastest and current way is to use Pillow, installed via pip install Pillow.

The code is then:

from PIL import Image
img = Image.open('input_file.jpg').convert('L')
img.save('output_file.jpg')

you can require the user to hit enter before closing the program... something like this works.

#include <iostream>
int main()
{
  std::cout << "Hello, World\n";
  std::cin.ignore();
  return 0;
}

The cin reads in user input, and the .ignore() function of cin tells the program to just ignore the input. The program will continue once the user hits enter.

In addition to solutions proposed, and in case you have a 1D range to 1D array, i prefer to process it through a function like below. The reason is simple: If for any reason your range is reduced to 1 element range, as far as i know the command Range().Value will not return a variant array but just a variant and you will not be able to assign a variant variable to a variant array (previously declared).

I had to convert a variable size range to a double array, and when the range was of 1 cell size, i was not able to use a construct like range().value so i proceed with a function like below.

Public Function Rng2Array(inputRange As Range) As Double()

    Dim out() As Double    
    ReDim out(inputRange.Columns.Count - 1)

    Dim cell As Range
    Dim i As Long
    For i = 0 To inputRange.Columns.Count - 1
        out(i) = inputRange(1, i + 1) 'loop over a range "row"
    Next

    Rng2Array = out  
End Function

SELECT p.MEMBSHIP_ID
FROM user_payments as p
WHERE USER_ID = 1 AND PAYM_DATE = (
    SELECT MAX(p2.PAYM_DATE)
    FROM user_payments as p2
    WHERE p2.USER_ID = p.USER_ID
)

To add to Preston's answer, here's the complete list of the HttpContent derived classes available in the standard library:

Credit: https://pfelix.wordpress.com/2012/01/16/the-new-system-net-http-classes-message-content/

There's also a supposed ObjectContent but I was unable to find it in ASP.NET Core.

Of course, you could skip the whole HttpContent thing all together with Microsoft.AspNet.WebApi.Client extensions (you'll have to do an import to get it to work in ASP.NET Core for now: https://github.com/aspnet/Home/issues/1558) and then you can do things like:

var response = await client.PostAsJsonAsync("AddNewArticle", new Article
{
    Title = "New Article Title",
    Body = "New Article Body"
});

Ports

The ports section will publish ports on the host. Docker will setup a forward for a specific port from the host network into the container. By default this is implemented with a userspace proxy process (docker-proxy) that listens on the first port, and forwards into the container, which needs to listen on the second point. If the container is not listening on the destination port, you will still see something listening on the host, but get a connection refused if you try to connect to that host port, from the failed forward into your container.

Note, the container must be listening on all network interfaces since this proxy is not running within the container's network namespace and cannot reach 127.0.0.1 inside the container. The IPv4 method for that is to configure your application to listen on 0.0.0.0.

Also note that published ports do not work in the opposite direction. You cannot connect to a service on the host from the container by publishing a port. Instead you'll find docker errors trying to listen to the already-in-use host port.

Expose

Expose is documentation. It sets metadata on the image, and when running, on the container too. Typically you configure this in the Dockerfile with the EXPOSE instruction, and it serves as documentation for the users running your image, for them to know on which ports by default your application will be listening. When configured with a compose file, this metadata is only set on the container. You can see the exposed ports when you run a docker inspect on the image or container.

There are a few tools that rely on exposed ports. In docker, the -P flag will publish all exposed ports onto ephemeral ports on the host. There are also various reverse proxies that will default to using an exposed port when sending traffic to your application if you do not explicitly set the container port.

Other than those external tools, expose has no impact at all on the networking between containers. You only need a common docker network, and connecting to the container port, to access one container from another. If that network is user created (e.g. not the default bridge network named bridge), you can use DNS to connect to the other containers.

I was/am in the same boat as you for different reasons (partly educational, partly constraints). I had to re-write all the containers of the standard library and the containers had to conform to the standard. That means, if I swap out my container with the stl version, the code would work the same. Which also meant that I had to re-write the iterators.

Anyway, I looked at EASTL. Apart from learning a ton about containers that I never learned all this time using the stl containers or through my undergraduate courses. The main reason is that EASTL is more readable than the stl counterpart (I found this is simply because of the lack of all the macros and straight forward coding style). There are some icky things in there (like #ifdefs for exceptions) but nothing to overwhelm you.

As others mentioned, look at cplusplus.com's reference on iterators and containers.

On local server your following query will work

DELIMITER |

CREATE PROCEDURE sample_sp_with_params (IN empId INT UNSIGNED, OUT oldName VARCHAR(20), INOUT newName VARCHAR(20))

BEGIN

SELECT `first name` into oldName FROM emp where id = empId;

UPDATE emp SET `first name`= newName where id = empId;

END

|

DELIMITER ;

but on production server it might not work. depend on mysql version you are using. I had a same problem on powweb server, i removed delimiter and begin keywords, it works fine. have a look at following query

CREATE PROCEDURE adminsections( IN adminId INT UNSIGNED ) SELECT tbl_adminusersection.ads_name, tbl_adminusersection.ads_controller FROM tbl_adminusersectionright LEFT JOIN tbl_adminusersection ON ( tbl_adminusersectionright.adsr_ads_id = tbl_adminusersection.ads_id ) LEFT JOIN tbl_adminusers ON ( tbl_adminusersectionright.adsr_adusr_id = tbl_adminusers.admusr_id ) WHERE tbl_adminusers.admusr_id = adminId;

You can try "SelectedIndexChanged", it will trigger the event even if the same item is selected.

Not a direct answer to this question but rather to the "issue" of $event.currentTarget apparently be set to null.

This is due to the fact that console.log shows deep mutable objects at the last state of execution, not at the state when console.log was called.

You can check this for more information: Consecutive calls to console.log produce inconsistent results

I am adding my answer, it is just an addon to the above, as for me I tried all the /n options and it didn't work, I saw my text is comming from server with double slash so I used this:

var fixedText = yourString.replace(/(\r\n|\n|\r|\\n)/gm, '');

Everybody that using: var myVar = 'token', is probably the worst idea. I can print it dirrectly in the console. You need to encrypt on the client side, then decrypt on server side.

The two methods previously described are not enough today. I personnally use :

input[type="text"]{
    background-color: transparent;
    border: 0px;
    outline: none;
    -webkit-box-shadow: none;
    -moz-box-shadow: none;
    box-shadow: none;
    width:5px;
    color:transparent;
    cursor:default;
}

It also removes the shadow set on some browsers, hide the text that could be input and make the cursor behave as if the input was not there.

You may want to set width to 0px also.

One solution that I've found is that you should have to change the .Net Framework back to v2.0 by Right Clicking on the site that you have manager under the Application Pools from the Advance Settings.

Apart from an understanding of the accesses amongst modules and their respective packages. I believe the crux of it lies in the Module System#Relaxed-strong-encapsulation and I would just cherry-pick the relevant parts of it to try and answer the question.

What defines an illegal reflective access and what circumstances trigger the warning?

To aid in the migration to Java-9, the strong encapsulation of the modules could be relaxed.

• An implementation may provide static access, i.e. by compiled bytecode.

• May provide a means to invoke its run-time system with one or more packages of one or more of its modules open to code in all unnamed modules, i.e. to code on the classpath. If the run-time system is invoked in this way, and if by doing so some invocations of the reflection APIs succeed where otherwise they would have failed.

In such cases, you've actually ended up making a reflective access which is "illegal" since in a pure modular world you were not meant to do such accesses.

How it all hangs together and what triggers the warning in what scenario?

This relaxation of the encapsulation is controlled at runtime by a new launcher option --illegal-access which by default in Java9 equals permit. The permit mode ensures

The first reflective-access operation to any such package causes a warning to be issued, but no warnings are issued after that point. This single warning describes how to enable further warnings. This warning cannot be suppressed.

The modes are configurable with values debug(message as well as stacktrace for every such access), warn(message for each such access), and deny(disables such operations).

Few things to debug and fix on applications would be:-

• Run it with --illegal-access=deny to get to know about and avoid opening packages from one module to another without a module declaration including such a directive(opens) or explicit use of --add-opens VM arg.
• Static references from compiled code to JDK-internal APIs could be identified using the jdeps tool with the --jdk-internals option

The warning message issued when an illegal reflective-access operation is detected has the following form:

WARNING: Illegal reflective access by $PERPETRATOR to $VICTIM

where:

$PERPETRATOR is the fully-qualified name of the type containing the code that invoked the reflective operation in question plus the code source (i.e., JAR-file path), if available, and

$VICTIM is a string that describes the member being accessed, including the fully-qualified name of the enclosing type

Questions for such a sample warning: = JDK9: An illegal reflective access operation has occurred. org.python.core.PySystemState

Last and an important note, while trying to ensure that you do not face such warnings and are future safe, all you need to do is ensure your modules are not making those illegal reflective accesses. :)

You can use Element.scrollIntoView() method as was mentioned above. If you leave it with no parameters inside you will have an instant ugly scroll. To prevent that you can add this parameter - behavior:"smooth".

Example:

document.getElementById('scroll-here-plz').scrollIntoView({behavior: "smooth", block: "start", inline: "nearest"});

Just replace scroll-here-plz with your div or element on a website. And if you see your element at the bottom of your window or the position is not what you would have expected, play with parameter block: "". You can use block: "start", block: "end" or block: "center".

Remember: Always use parameters inside an object {}.

If you would still have problems, go to https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView

There is detailed documentation for this method.

I got the same error when I added the applicationinitialization module with lots of initializationpages and deployed it on Azure app. The issue turned out to be duplicate entries in my applicationinitialization module. I din't see any errors in the logs so it was hard to troubleshoot. Below is an example of the error code:

  <configuration>
  <system.webServer>
    <applicationInitialization doAppInitAfterRestart="true" skipManagedModules="true">
      <add initializationPage="/init1.aspx?call=2"/>
      <add initializationPage="/init1.aspx?call=2" />
    </applicationInitialization>
  </system.webServer>

Make sure there are no duplicate entries because those will be treated as duplicate keys which are not allowed and will result in "Cannot add duplicate collection entry" error for web.config.

In PHP, passing by reference (&) is ... controversial. I recommend not using it unless you know why you need it and test the results.

I would recommend doing the following:

foreach ($fields as $key => $field) {
    if ($field['required'] && strlen($_POST[$field['name']]) <= 0) {
        $fields[$key]['value'] = "Some error";
    }
}

So basically use $field when you need the values, and $fields[$key] when you need to change the data.

How about this:

from pandas import *

idx = Int64Index([171, 174, 173])
df = DataFrame(index = idx, data =([1,2,3]))
print df

It gives me:

     0
171  1
174  2
173  3

Is this what you are looking for?

I faced the same issue and successfully solved it. My use-case is this.

"Post JSON data to the server and receive an excel file. That excel file is created by the server and returned as a response to the client. Download that response as a file with custom name in browser"

$("#my-button").on("click", function(){

// Data to post
data = {
    ids: [1, 2, 3, 4, 5]
};

// Use XMLHttpRequest instead of Jquery $ajax
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    var a;
    if (xhttp.readyState === 4 && xhttp.status === 200) {
        // Trick for making downloadable link
        a = document.createElement('a');
        a.href = window.URL.createObjectURL(xhttp.response);
        // Give filename you wish to download
        a.download = "test-file.xls";
        a.style.display = 'none';
        document.body.appendChild(a);
        a.click();
    }
};
// Post data to URL which handles post request
xhttp.open("POST", excelDownloadUrl);
xhttp.setRequestHeader("Content-Type", "application/json");
// You should set responseType as blob for binary responses
xhttp.responseType = 'blob';
xhttp.send(JSON.stringify(data));
});

The above snippet is just doing following

• Posting an array as JSON to the server using XMLHttpRequest.
• After fetching content as a blob(binary), we are creating a downloadable URL and attaching it to invisible "a" link then clicking it. I did a POST request here. Instead, you can go for a simple GET too. We cannot download the file through Ajax, must use XMLHttpRequest.

Here we need to carefully set few things on the server side. I set few headers in Python Django HttpResponse. You need to set them accordingly if you use other programming languages.

# In python django code
response = HttpResponse(file_content, content_type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")

Since I download xls(excel) here, I adjusted contentType to above one. You need to set it according to your file type. You can use this technique to download any kind of files.

df.drop(labels=df[df.index % 3 != 0].index, axis=0) #  every 3rd row (mod 3)

How can I undo every change made to my directory after the last commit, including deleting added files, resetting modified files, and adding back deleted files?

1. You can undo changes to tracked files with:

   git reset HEAD --hard
   

2. You can remove untracked files with:

   git clean -f
   

3. You can remove untracked files and directories with:

   git clean -fd
   

   but you can't undo change to untracked files.

4. You can remove ignored and untracked files and directories

   git clean -fdx
   

   but you can't undo change to ignored files.

You can also set clean.requireForce to false:

git config --global --add clean.requireForce false

to avoid using -f (--force) when you use git clean.

Current answers are perfectly correct on how to create the aggregations, but none actually address the column alias/renaming that is also requested in the question.

Typically, this is how I handle this case:

val dimensionFields = List("col1")
val metrics = List("col2", "col3", "col4")
val columnOfInterests = dimensions ++ metrics

val df = spark.read.table("some_table"). 
    .select(columnOfInterests.map(c => col(c)):_*)
    .groupBy(dimensions.map(d => col(d)): _*)
    .agg(metrics.map( m => m -> "sum").toMap)
    .toDF(columnOfInterests:_*)    // that's the interesting part

The last line essentially renames every columns of the aggregated dataframe to the original fields, essentially changing sum(col2) and sum(col3) to simply col2 and col3.

Auth::routes() is just a helper class that helps you generate all the routes required for user authentication. You can browse the code here https://github.com/laravel/framework/blob/5.3/src/Illuminate/Routing/Router.php instead.

Here are the routes

// Authentication Routes...
$this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
$this->post('login', 'Auth\LoginController@login');
$this->post('logout', 'Auth\LoginController@logout')->name('logout');

// Registration Routes...
$this->get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
$this->post('register', 'Auth\RegisterController@register');

// Password Reset Routes...
$this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm');
$this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
$this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm');
$this->post('password/reset', 'Auth\ResetPasswordController@reset');

The standard does say this:

Programming languages vary widely on whether they support objects, and if so, what characteristics and constraints the objects offer. The models of object systems can be wildly divergent and are continuing to evolve. JSON instead provides a simple notation for expressing collections of name/value pairs. Most programming languages will have some feature for representing such collections, which can go by names like record, struct, dict, map, hash, or object.

The bug is in node.js at least. This code succeeds in node.js.

try {
     var json = {"name":"n","name":"v"};
     console.log(json); // outputs { name: 'v' }
} catch (e) {
     console.log(e);
}

Here is the tutorial to install GBD.

Usually GNU Debugger might not be in your computer, so you would install it first. The installation steps are basic "configure", "make", and "make install".

Once installed, try which gdb in terminal, to find the executable path of GDB.

First, I recommend that you use WCF, .NET Remoting, or some other higher-level communication abstraction. The learning curve for "simple" sockets is nearly as high as WCF, because there are so many non-obvious pitfalls when using TCP/IP directly.

If you decide to continue down the TCP/IP path, then review my .NET TCP/IP FAQ, particularly the sections on message framing and application protocol specifications.

Also, use asynchronous socket APIs. The synchronous APIs do not scale and in some error situations may cause deadlocks. The synchronous APIs make for pretty little example code, but real-world production-quality code uses the asynchronous APIs.

I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:

1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)

2: Run your formula

3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank

4: Replace All

Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.

Removing the JRE System Library and adding the default one worked for me.

Formats like

date9. 

or

mmddyy10. 

are not valid for input command while converting text to a sas date. You can use

Date = input( cdate , ANYDTDTE11.);

or

Date = input( cdate , ANYDTDTE10.); 

for conversion.

For JSON data, it's much easier to POST it as "application/json" content-type. If you use GET, you have to URL-encode the JSON in a parameter and it's kind of messy. Also, there is no size limit when you do POST. GET's size if very limited (4K at most).

Are u sure u want to remove only last character. What if the user press backspace from the middle of the word.. Its better to get the value from the field and replace the divs html. On keyup

$("#div").html($("#input").val());

Rather do it this way:

// reads resources regardless of their size
public byte[] getResource(int id, Context context) throws IOException {
    Resources resources = context.getResources();
    InputStream is = resources.openRawResource(id);

    ByteArrayOutputStream bout = new ByteArrayOutputStream();

    byte[] readBuffer = new byte[4 * 1024];

    try {
        int read;
        do {
            read = is.read(readBuffer, 0, readBuffer.length);
            if(read == -1) {
                break;
            }
            bout.write(readBuffer, 0, read);
        } while(true);

        return bout.toByteArray();
    } finally {
        is.close();
    }
}

    // reads a string resource
public String getStringResource(int id, Charset encoding) throws IOException {
    return new String(getResource(id, getContext()), encoding);
}

    // reads an UTF-8 string resource
public String getStringResource(int id) throws IOException {
    return new String(getResource(id, getContext()), Charset.forName("UTF-8"));
}

From an Activity, add

public byte[] getResource(int id) throws IOException {
        return getResource(id, this);
}

or from a test case, add

public byte[] getResource(int id) throws IOException {
        return getResource(id, getContext());
}

And watch your error handling - don't catch and ignore exceptions when your resources must exist or something is (very?) wrong.

Shortly: gene_name[x] is a mutable object so it cannot be hashed. To use an object as a key in a dictionary, python needs to use its hash value, and that's why you get an error.

Further explanation:

Mutable objects are objects which value can be changed. For example, list is a mutable object, since you can append to it. int is an immutable object, because you can't change it. When you do:

a = 5;
a = 3;

You don't change the value of a, you create a new object and make a point to its value.

Mutable objects cannot be hashed. See this answer.

To solve your problem, you should use immutable objects as keys in your dictionary. For example: tuple, string, int.

I believe this snippet will also be helpful in a situation where the dates comparison spans more than two entries.

static final int COMPARE_EARLIEST = 0;

static final int COMPARE_MOST_RECENT = 1;


public LocalDate getTargetDate(List<LocalDate> datesList, int comparatorType) { 
   LocalDate refDate = null;
   switch(comparatorType)
   {
       case COMPARE_EARLIEST:         
       //returns the most earliest of the date entries
          refDate = (LocalDate) datesList.stream().min(Comparator.comparing(item -> 
                      item.toDateTimeAtCurrentTime())).get();
          break;

       case COMPARE_MOST_RECENT:
          //returns the most recent of the date entries 
          refDate = (LocalDate) datesList.stream().max(Comparator.comparing(item -> 
                    item.toDateTimeAtCurrentTime())).get();
          break;
   }

   return refDate;
}

player['score'] is your problem. player is apparently a list which means that there is no 'score' element. Instead you would do something like:

name, score = player[0], player[1]
return name + ' ' + str(score)

Of course, you would have to know the list indices (those are the 0 and 1 in my example).

Something like player['score'] is allowed in python, but player would have to be a dict.

You can read more about both lists and dicts in the python documentation.

you can use this too

.parent:hover * {
   /* ... */
}

new Long(Integer.longValue());

or

new Long(Integer.toString());

I used this simple code:

-- I like this as the data type and the format remains consistent with a date time data type

;with cte as(
    select 
        cast(utcdate as date) UtcDay, DATEPART(hour, utcdate) UtcHour, count(*) as Counts
    from dbo.mytable cd 
    where utcdate between '2014-01-14' and '2014-01-15'
    group by
        cast(utcdate as date), DATEPART(hour, utcdate)
)
select dateadd(hour, utchour, cast(utcday as datetime)) as UTCDateHour, Counts
from cte

from a "Mr. Make post" https://www.cmcrossroads.com/article/printing-value-makefile-variable

Add the following rule to your Makefile:

print-%  : ; @echo $* = $($*)

Then, if you want to find out the value of a makefile variable, just:

make print-VARIABLE

and it will return:

VARIABLE = the_value_of_the_variable

Taken from the Multimarkdown Users Guide (thanks to @MultiMarkdown on Twitter for pointing it out)

[Some Text][]will link to a header named “Some Text”
e.g.

### Some Text ###

An optional label of your choosing to help disambiguate cases where multiple headers have the same title:

### Overview [MultiMarkdownOverview] ##

This allows you to use [MultiMarkdownOverview] to refer to this section specifically, and not another section named Overview. This works with atx- or settext-style headers.

If you have already defined an anchor using the same id that is used by a header, then the defined anchor takes precedence.

In addition to headers within the document, you can provide labels for images and tables which can then be used for cross-references as well.

The answers presented before mine provide apt solutions to the problem, however, I feel that it is important to understand why this error results:

The Session property of the Page returns an instance of type HttpSessionState relative to that particular request. Page.Session is actually equivalent to calling Page.Context.Session.

MSDN explains how this is possible:

Because ASP.NET pages contain a default reference to the System.Web namespace (which contains the HttpContext class), you can reference the members of HttpContext on an .aspx page without the fully qualified class reference to HttpContext.

However, When you try to access this property within a class in App_Code, the property will not be available to you unless your class derives from the Page Class.

My solution to this oft-encountered scenario is that I never pass page objects to classes. I would rather extract the required objects from the page Session and pass them to the Class in the form of a name-value collection / Array / List, depending on the case.

There are two types of contexts we are dealing with:

1: root context (parent context. Typically include all jdbc(ORM, Hibernate) initialisation and other spring security related configuration)

2: individual servlet context (child context.Typically Dispatcher Servlet Context and initialise all beans related to spring-mvc (controllers , URL Mapping etc)).

Here is an example of web.xml which includes multiple application context file

I have found out that if you remove Microsoft.CSharp assembly as a reference in the project, you will get this error.

If you want to do it line by line:

Dim sFileText As String
Dim iInputFile As Integer, iOutputFile as integer

iInputFile = FreeFile
Open "C:\Clients\Converter\Clockings.mis" For Input As #iInputFile 
iOutputFile = FreeFile
Open "C:\Clients\Converter\2.txt" For Output As #iOutputFile 
Do While Not EOF(iInputFile)
   Line Input #iInputFile , sFileText
   ' sFileTextis a single line of the original file
   ' you can append anything to it before writing to the other file
   Print #iOutputFile, sFileText 
Loop
Close #iInputFile 
Close #iOutputFile 

There's a pretty nice interface for this in processing, which is kind of a pidgin java designed for graphics. It gets used in some image recognition work, such as that link.

Depending on what you need out of it, you might be able to load the video library that's used there in java, or if you're just playing around with it you might be able to get by using processing itself.

For anyone stumbling across this question refer to this documentation from MS - it has really good details regarding FormsAuthentication Timeout setting.

This doc explains in detail about the comment bmode is making in the Accepted Answer - about the Persistent Cookie (Session vs Expires)

https://docs.microsoft.com/en-us/aspnet/web-forms/overview/older-versions-security/introduction/forms-authentication-configuration-and-advanced-topics-cs#specifying-the-tickets-timeout-value

$( this ).find( 'li.target' ).css("border", "3px double red");

or

$( this ).children( 'li.target' ).css("border", "3px double red");

Use children for immediate descendants, or find for deeper elements.

Getting month range with .Net API (just another way):

DateTime date = ...
var firstDayOfMonth = new DateTime(date.Year, date.Month, 1);
var lastDayOfMonth = new DateTime(date.Year, date.Month, DateTime.DaysInMonth(date.Year, date.Month));

Your problem is that you are naming your component class Date. When you call new Date() within your class, it won't create an instance of the Date you expect it to create (which is likely this Date)- it will try to create an instance of your component class. Then the constructor will try to create another instance, and another instance, and another instance... Until you run out of stack space and get the error you're seeing.

If you want to use Date within your class, try naming your class something different such as Calendar or DateComponent.

The reason for this is how JavaScript deals with name scope: Whenever you create a new named entity, if there is already an entity with that name in scope, that name will stop referring to the previous entity and start referring to your new entity. So if you use the name Date within a class named Date, the name Date will refer to that class and not to any object named Date which existed before the class definition started.

I have noticed also that even if you specify your website under secion - Website With Facebook Login -> Site url as e.g. http://example.com, but if your App Domains section is empty, and you open website as www.example.com you will get this error, too. To avoid it in "App Domains" section write example.com, that will allow subdomains, like www.example.com, something.example.com etc

All the setting are stored in .metadata file in your workspace delete this and you are good to go

Late in the game... :)

A very simple solution is to patch the json module default. For example:

import json
import datetime

json.JSONEncoder.default = lambda self,obj: (obj.isoformat() if isinstance(obj, datetime.datetime) else None)

Now, you can use json.dumps() as if it had always supported datetime...

json.dumps({'created':datetime.datetime.now()})

This makes sense if you require this extension to the json module to always kick in and wish to not change the way you or others use json serialization (either in existing code or not).

Note that some may consider patching libraries in that way as bad practice. Special care need to be taken in case you may wish to extend your application in more than one way - is such a case, I suggest to use the solution by ramen or JT and choose the proper json extension in each case.

Use following code,I have tested it and its working

var prev_val;
$('.dropdown').focus(function() {
    prev_val = $(this).val();
}).change(function(){
            $(this).unbind('focus');
            var conf = confirm('Are you sure want to change status ?');

            if(conf == true){
                //your code
            }
            else{
                $(this).val(prev_val);
                $(this).bind('focus');
                return false;
            }
});

Can't import all at once but can use following combination:

F2 --> Next highlighted error.

This error means that file was not found. Either path is wrong or file is not present where you want it to be. Try to access it by entering source address in your browser to check if it really is there. Browse the directories on server to ensure the path is correct. You may even copy and paste the relative path to be certain it is alright.

I like using the static initializer "technique" when I have a concrete realization of an abstract class that has defined an initializing constructor but no default constructor but I want my subclass to have a default constructor.

For example:

public abstract class Shape {

    public static final String COLOR_KEY = "color_key";
    public static final String OPAQUE_KEY = "opaque_key";

    private final String color;
    private final Boolean opaque;

    /**
     * Initializing constructor - note no default constructor.
     *
     * @param properties a collection of Shape properties
     */
    public Shape(Map<String, Object> properties) {
        color = ((String) properties.getOrDefault(COLOR_KEY, "black"));
        opaque = (Boolean) properties.getOrDefault(OPAQUE_KEY, false);
    }

    /**
     * Color property accessor method.
     *
     * @return the color of this Shape
     */
    public String getColor() {
        return color;
    }

    /**
     * Opaque property accessor method.
     *
     * @return true if this Shape is opaque, false otherwise
     */
    public Boolean isOpaque() {
        return opaque;
    }
}

and my concrete realization of this class -- but it wants/needs a default constructor:

public class SquareShapeImpl extends Shape {

    private static final Map<String, Object> DEFAULT_PROPS = new HashMap<>();

    static {
        DEFAULT_PROPS.put(Shape.COLOR_KEY, "yellow");
        DEFAULT_PROPS.put(Shape.OPAQUE_KEY, false);
    }

    /**
     * Default constructor -- intializes this square to be a translucent yellow
     */
    public SquareShapeImpl() {
        // the static initializer was useful here because the call to 
        // this(...) must be the first statement in this constructor
        // i.e., we can't be mucking around and creating a map here
        this(DEFAULT_PROPS);
    }

    /**
     * Initializing constructor -- create a Square with the given
     * collection of properties.
     *
     * @param props a collection of properties for this SquareShapeImpl
     */
    public SquareShapeImpl(Map<String, Object> props) {
        super(props);
    }
}

then to use this default constructor, we simply do:

public class StaticInitDemo {

    public static void main(String[] args) {

        // create a translucent, yellow square...
        Shape defaultSquare = new SquareShapeImpl();

        // etc...
    }
}

It depends if you're using EF Core 2.1 or EF Core 3 and higher versions.

If you're using EF Core 2.1

If you're using EF Core 2.1 Release Candidate 1 available since 7 may 2018, you can take advantage of the proposed new feature which is Query type.

What is query type?

In addition to entity types, an EF Core model can contain query types, which can be used to carry out database queries against data that isn't mapped to entity types.

When to use query type?

Serving as the return type for ad hoc FromSql() queries.

Mapping to database views.

Mapping to tables that do not have a primary key defined.

Mapping to queries defined in the model.

So you no longer need to do all the hacks or workarounds proposed as answers to your question. Just follow these steps:

First you defined a new property of type DbQuery<T> where T is the type of the class that will carry the column values of your SQL query. So in your DbContext you'll have this:

public DbQuery<SomeModel> SomeModels { get; set; }

Secondly use FromSql method like you do with DbSet<T>:

var result = context.SomeModels.FromSql("SQL_SCRIPT").ToList();
var result = await context.SomeModels.FromSql("SQL_SCRIPT").ToListAsync();

Also note that DdContexts are partial classes, so you can create one or more separate files to organize your 'raw SQL DbQuery' definitions as best suits you.

If you're using EF Core 3.0 and higher versions

Query type is now known as Keyless entity type. As said above query types were introduced in EF Core 2.1. If you're using EF Core 3.0 or higher version you should now consider using keyless entity types because query types are now marked as obsolete.

This feature was added in EF Core 2.1 under the name of query types. In EF Core 3.0 the concept was renamed to keyless entity types. The [Keyless] Data Annotation became available in EFCore 5.0.

We still have the same scenarios as for query types for when to use keyless entity type.

So to use it you need to first mark your class SomeModel with [Keyless] data annotation or through fluent configuration with .HasNoKey() method call like below:

public DbSet<SomeModel> SomeModels { get; set; }

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<SomeModel>().HasNoKey();
}

After that configuration, you can use one of the methods explained here to execute your SQL query. For example you can use this one:

var result = context.SomeModels.FromSqlRaw("SQL SCRIPT").ToList();

If you want to use the same date format among multiple threads, declare it as a static and synchronize on the instance variable when using it...

static private SimpleDateFormat sdf = new SimpleDateFormat("....");

synchronized(sdf)
{
   // use the instance here to format a date
}


// The above makes it thread safe

If you are using Guava library it's possible to do:

        SetView<Record> added = Sets.difference(secondSet, firstSet);
        SetView<Record> removed = Sets.difference(firstSet, secondSet);

And then make a conclusion based on these.

This code is better rewritten as:

for( Map.Entry me : entrys.entrySet() )
{
    this.add( (Component) me.getValue() );
}

and it is equivalent to:

for( Component comp : entrys.getValues() )
{
    this.add( comp );
}

When you enumerate the entries of a map, the iteration yields a series of objects which implement the Map.Entry interface. Each one of these objects contains a key and a value.

It is supposed to be slightly more efficient to enumerate the entries of a map than to enumerate its values, but this factoid presumes that your Map is a HashMap, and also presumes knowledge of the inner workings (implementation details) of the HashMap class. What can be said with a bit more certainty is that no matter how your map is implemented, (whether it is a HashMap or something else,) if you need both the key and the value of the map, then enumerating the entries is going to be more efficient than enumerating the keys and then for each key invoking the map again in order to look up the corresponding value.

From the Testivus posting I think the answer context should be the second programmer. Having said this from a practical point of view we need parameter / goals to strive for. I consider that this can be "tested" in an Agile process by analyzing the code we have the architecture, functionality (user stories), and then come up with a number. Based on my experience in the Telecom area I would say that 60% is a good value to check.

I followed the steps at https://www.w3schools.com/php/php_file_upload.asp and http://www.w3bees.com/2013/03/resize-image-while-upload-using-php.html to produce this solution:

In my view (I am using the MVC paradigm, but it could be your .html or .php file, or the technology that you use for your front-end):

<form action="../../photos/upload.php" method="post" enctype="multipart/form-data">
<label for="quantity">Width:</label>
  <input type="number" id="picture_width" name="picture_width" min="10" max="800" step="1" value="500">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>

My upload.php:

<?php
/* Get original image x y*/
list($w, $h) = getimagesize($_FILES['fileToUpload']['tmp_name']);
$new_height=$h*$_POST['picture_width']/$w;
/* calculate new image size with ratio */
$ratio = max($_POST['picture_width']/$w, $new_height/$h);
$h = ceil($new_height / $ratio);
$x = ($w - $_POST['picture_width'] / $ratio) / 2;
$w = ceil($_POST['picture_width'] / $ratio);
/* new file name */
//$path = 'uploads/'.$_POST['picture_width'].'x'.$new_height.'_'.basename($_FILES['fileToUpload']['name']);
$path = 'uploads/'.basename($_FILES['fileToUpload']['name']);
/* read binary data from image file */
$imgString = file_get_contents($_FILES['fileToUpload']['tmp_name']);
/* create image from string */
$image = imagecreatefromstring($imgString);
$tmp = imagecreatetruecolor($_POST['picture_width'], $new_height);
imagecopyresampled($tmp, $image,
    0, 0,
    $x, 0,
    $_POST['picture_width'], $new_height,
    $w, $h);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($path,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        //echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        //echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($path)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
    // if everything is ok, try to upload file
} else {
    /* Save image */
    switch ($_FILES['fileToUpload']['type']) {
        case 'image/jpeg':
            imagejpeg($tmp, $path, 100);
            break;
        case 'image/png':
            imagepng($tmp, $path, 0);
            break;
        case 'image/gif':
            imagegif($tmp, $path);
            break;
        default:
            exit;
            break;
    }
    echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    /* cleanup memory */
    imagedestroy($image);
    imagedestroy($tmp);
}
?>

The name of the folder where pictures are stored is called 'uploads/'. You need to have that folder previously created and that is where you will see your pictures. It works great for me.

NOTE: This is my form:

The code is uploading and resizing pictures properly. I used this link as a guide: http://www.w3bees.com/2013/03/resize-image-while-upload-using-php.html. I modified it because in that code they specify both width and height of resized pictures. In my case, I only wanted to specify width. The height I automatically calculated it proportionally, just keeping proper picture proportions. Everything works perfectly. I hope this helps.

 using (FileStream fs = File.Create(path))
 {

 }

Will create or overwrite a file.

Please refer below Ajax overview:

http://msdn.microsoft.com/en-us/library/bb386454.aspx

#include <iostream>
#include <sstream>

std::string input = "abc,def,ghi";
std::istringstream ss(input);
std::string token;

while(std::getline(ss, token, ',')) {
    std::cout << token << '\n';
}

abc
def
ghi

Sometimes most of the registration and login page need to validate email. In this example you will learn simple email validation. First take a text input in html and a button input like this

<input type='text' id='txtEmail'/>
<input type='submit' name='submit' onclick='checkEmail();'/>

<script>
    function checkEmail() {
        var email = document.getElementById('txtEmail');
        var filter = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
        if (!filter.test(email.value)) {
            alert('Please provide a valid email address');
            email.focus;
            return false;
        }
    }
</script>

you can also check using this regular expression

<input type='text' id='txtEmail'/>
<input type='submit' name='submit' onclick='checkEmail();'/>

<script>
    function checkEmail() {

        var email = document.getElementById('txtEmail');
        var filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;

        if (!filter.test(email.value)) {
            alert('Please provide a valid email address');
            email.focus;
            return false;
        }
    }
</script>

Check this demo output which you can check here

function checkEmail() {_x000D_
        var email = document.getElementById('txtEmail');_x000D_
        var filter = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;_x000D_
        if (!filter.test(email.value)) {_x000D_
            alert('Please provide a valid email address');_x000D_
            email.focus;_x000D_
            return false;_x000D_
        }_x000D_
    }

<input type='text' id='txtEmail'/>_x000D_
<input type='submit' name='submit' onclick='checkEmail();'/>

if email invalid then give alert message , if valid email then no alert message . for more info about regular expression

hope it will help you

Using TypedValue is a much cleaner way of converting to pixels compared to manually calculating:

float paddingDp = 10f;
// Convert to pixels
int paddingPx = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, paddingDp, context.getResources().getDisplayMetrics());
view.setPadding(paddingPx, paddingPx, paddingPx, paddingPx);

Essentially, TypedValue.applyDimension converts the desired padding into pixels appropriately depending on the current device's display properties.

For more info see: TypedValue.applyDimension Docs.

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

You need a root node

<?xml version="1.0" encoding="ISO-8859-1"?>

Thanks to everyone above, but this is now fixed. For the benefit of others the most significant error was in aligning the three namespaces as suggested by Ian.

For completeness, here is the corrected XML and XSD

Here is the XML, with the typos corrected (sorry for any confusion caused by tardiness)

Thanks again to everyone, I hope this is of use to somebody else in the future.

I think you're a little confused. PYTHONPATH sets the search path for importing python modules, not for executing them like you're trying.

PYTHONPATH Augment the default search path for module files. The format is the same as the shell’s PATH: one or more directory pathnames separated by os.pathsep (e.g. colons on Unix or semicolons on Windows). Non-existent directories are silently ignored.

In addition to normal directories, individual PYTHONPATH entries may refer to zipfiles containing pure Python modules (in either source or compiled form). Extension modules cannot be imported from zipfiles.

The default search path is installation dependent, but generally begins with prefix/lib/pythonversion (see PYTHONHOME above). It is always appended to PYTHONPATH.

An additional directory will be inserted in the search path in front of PYTHONPATH as described above under Interface options. The search path can be manipulated from within a Python program as the variable sys.path.

http://docs.python.org/2/using/cmdline.html#envvar-PYTHONPATH

What you're looking for is PATH.

export PATH=$PATH:/home/randy/lib/python 

However, to run your python script as a program, you also need to set a shebang for Python in the first line. Something like this should work:

#!/usr/bin/env python

And give execution privileges to it:

chmod +x /home/randy/lib/python/gbmx.py

Then you should be able to simply run gmbx.py from anywhere.

Check that your dependencies were compiled without -f-nortti.

For some projects you have to set it explicitly, like in RocksDB:

USE_RTTI=1 make shared_lib -j4

$.each(["input[type=text][value=]", "textarea[value=]"], function (index, element) {
              //only empty input and textarea will come here
});

go get will install the package in the first directory listed at GOPATH (an environment variable which might contain a colon separated list of directories). You can use go get -u to update existing packages.

You can also use go get -u all to update all packages in your GOPATH

For larger projects, it might be reasonable to create different GOPATHs for each project, so that updating a library in project A wont cause issues in project B.

Type go help gopath to find out more about the GOPATH environment variable.

Setting PYTHONPATH can also help with this problem.

Here is how it can be done on Windows

set PYTHONPATH=.

To calculate the mean, loop through the list/array of numbers, keeping track of the partial sums and the length. Then return the sum/length.

double sum = 0.0;
int length = 0;

for( double number : numbers ) {
    sum += number;
    length++;
}

return sum/length;

Variance is calculated similarly. Standard deviation is simply the square root of the variance:

double stddev = Math.sqrt( variance );

Here are some other files that may be left behind by setuptools:

MANIFEST
*.egg-info

I recommend using .htaccess. You only need to add:

DirectoryIndex home.php

or whatever page name you want to have for it.

EDIT: basic htaccess tutorial.

1) Create .htaccess file in the directory where you want to change the index file.

• no extension
• . in front, to ensure it is a "hidden" file

Enter the line above in there. There will likely be many, many other things you will add to this (AddTypes for webfonts / media files, caching for headers, gzip declaration for compression, etc.), but that one line declares your new "home" page.

2) Set server to allow reading of .htaccess files (may only be needed on your localhost, if your hosting servce defaults to allow it as most do)

Assuming you have access, go to your server's enabled site location. I run a Debian server for development, and the default site setup is at /etc/apache2/sites-available/default for Debian / Ubuntu. Not sure what server you run, but just search for "sites-available" and go into the "default" document. In there you will see an entry for Directory. Modify it to look like this:

<Directory /var/www/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    Order allow,deny
    allow from all
</Directory>

Then restart your apache server. Again, not sure about your server, but the command on Debian / Ubuntu is:

sudo service apache2 restart

Technically you only need to reload, but I restart just because I feel safer with a full refresh like that.

Once that is done, your site should be reading from your .htaccess file, and you should have a new default home page! A side note, if you have a sub-directory that runs a site (like an admin section or something) and you want to have a different "home page" for that directory, you can just plop another .htaccess file in that sub-site's root and it will overwrite the declaration in the parent.

Using the C# language constructs, you cannot explicitly call the base function from outside the scope of A or B. If you really need to do that, then there is a flaw in your design - i.e. that function shouldn't be virtual to begin with, or part of the base function should be extracted to a separate non-virtual function.

You can from inside B.X however call A.X

class B : A
{
  override void X() { 
    base.X();
    Console.WriteLine("y"); 
  }
}

But that's something else.

As Sasha Truf points out in this answer, you can do it through IL. You can probably also accomplish it through reflection, as mhand points out in the comments.

You need to use the android:background property , eg

android:background="@color/white"

Also you need to add a value for white in the strings.xml

<color name="white">#FFFFFF</color>

Edit : 18th Nov 2012

The first two letters of an 8 letter color code provide the alpha value, if you are using the html 6 letter color notation the color is opaque.

Eg :

Access 2007 can lose the CurrentDb: see http://support.microsoft.com/kb/167173, so in the event of getting "Object Invalid or no longer set" with the examples, use:

Dim db as Database
Dim rs As DAO.Recordset
Set db = CurrentDB
Set rs = db.OpenRecordset("SELECT * FROM myTable")

                case Phase.Days:
                    if (current.AddDays(days + 1) > date2)
                    {
                        current = current.AddDays(days);
                        var timespan = date2 - current;
                        span = new DateTimeSpan(years, months, days, timespan.Hours, timespan.Minutes, timespan.Seconds, timespan.Milliseconds);
                        phase = Phase.Done;
                    }
                    else
                    {
                        days++;
                    }
                    break;
            }
        }

        return span;
    }
}

use the helper function in laravel 5.1 instead:

return response()->json(['name' => 'Abigail', 'state' => 'CA']);

This will create an instance of \Illuminate\Routing\ResponseFactory. See the phpDocs for possible parameters below:

/**
* Return a new JSON response from the application.
*
* @param string|array $data
* @param int $status
* @param array $headers
* @param int $options
* @return \Symfony\Component\HttpFoundation\Response 
* @static 
*/
public static function json($data = array(), $status = 200, $headers = array(), $options = 0){

    return \Illuminate\Routing\ResponseFactory::json($data, $status, $headers, $options);
}

I know this is old, but I've tested this in many ways and it hasn't let me down yet, unless someone can tell me otherwise.

Row number

Row = ws.Cells.Find(What:="*", After:=[A1] , SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row

Column Letter

ColumnLetter = Split(ws.Cells.Find(What:="*", After:=[A1], SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Cells.Address(1, 0), "$")(0)

Column Number

ColumnNumber = ws.Cells.Find(What:="*", After:=[A1], SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column

the answers above doesn't work in my case. You need to specify utf-8 in meta tag

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    </head>
    <body>
        <!-- you content goes here -->
    </body>
</html>

You forgot the .class:

if (value.getClass() == Integer.class) {
    System.out.println("This is an Integer");
} 
else if (value.getClass() == String.class) {
    System.out.println("This is a String");
}
else if (value.getClass() == Float.class) {
    System.out.println("This is a Float");
}

Note that this kind of code is usually the sign of a poor OO design.

Also note that comparing the class of an object with a class and using instanceof is not the same thing. For example:

"foo".getClass() == Object.class

is false, whereas

"foo" instanceof Object

is true.

Whether one or the other must be used depends on your requirements.

I got some better solutions:

gc log.txt -ReadCount 5 | %{$_;throw "pipeline end!"} # head
gc log.txt | %{$num=0;}{$num++;"$num $_"}             # cat -n
gc log.txt | %{$num=0;}{$num++; if($num -gt 2 -and $num -lt 7){"$num $_"}} # sed

It's called and and or in Python.

is possible with a lambda function

@{
string controllerAction = ViewContext.RouteData.Values["Controller"].ToString() + ViewContext.RouteData.Values["Action"].ToString();
    Func<string, string> IsSelected= x => x==controllerAction ? "active" : "";
}

then usage

 @Html.ActionLink("Inicio", "Index", "Home", new { area = "" }, new { @class = IsSelected("HomeIndex")})

@Barry Kelly and @Andrew Hare, actually, I don't think multiplying is the most clear way to do this (alltough correct).

An Int32 "formatted" IP address can be seen as the following structure

[StructLayout(LayoutKind.Sequential, Pack = 1)] 
struct IPv4Address
{
   public Byte A;
   public Byte B;
   public Byte C;
   public Byte D;
} 
// to actually cast it from or to an int32 I think you 
// need to reverse the fields due to little endian

So to convert the ip address 64.233.187.99 you could do:

(64  = 0x40) << 24 == 0x40000000
(233 = 0xE9) << 16 == 0x00E90000
(187 = 0xBB) << 8  == 0x0000BB00
(99  = 0x63)       == 0x00000063
                      ---------- =|
                      0x40E9BB63

so you could add them up using + or you could binairy or them together. Resulting in 0x40E9BB63 which is 1089059683. (In my opinion looking in hex it's much easier to see the bytes)

So you could write the function as:

int ipToInt(int first, int second, 
    int third, int fourth)
{
    return (first << 24) | (second << 16) | (third << 8) | (fourth);
}

The main difference is sorting accuracy (when comparing characters in the language) and performance. The only special one is utf8_bin which is for comparing characters in binary format.

utf8_general_ci is somewhat faster than utf8_unicode_ci, but less accurate (for sorting). The specific language utf8 encoding (such as utf8_swedish_ci) contain additional language rules that make them the most accurate to sort for those languages. Most of the time I use utf8_unicode_ci (I prefer accuracy to small performance improvements), unless I have a good reason to prefer a specific language.

If you are using Postgres (and since we're in 2017 now) you might want to give their :money column type a try.

Put http.request.method == "POST" in the display filter of wireshark to only show POST requests. Click on the packet, then expand the Hypertext Transfer Protocol field. The POST data will be right there on top.

The problem with some of the suggested solutions is that they don't take into account various float number formats. The following function does it:

public bool IsNumber(String value)
{
    double d;
    if (string.IsNullOrWhiteSpace(value)) 
        return false; 
    else        
        return double.TryParse(value.Trim(), System.Globalization.NumberStyles.Any,
                            System.Globalization.CultureInfo.InvariantCulture, out d);
}

It assumes that the various float number styles such es decimal point (English) and decima comma (German) are all allowed. If that is not the case, change the number styles paramater. Note that Any does not include hex mumbers, because the type double does not support it.

Alternatively, I checked the pom.xml and changed

<java.version>1.8</java.version>

to

<java.version>1.7</java.version>

This is my solution for your reference:

struct Foo
{
    Foo(){}//used to make compiler happy!
    Foo(int x){/*...*/}
};

struct Bar
{
    Foo foo[3];

    Bar()
    {
        //initialize foo array here:
        for(int i=0;i<3;++i)
        {
            foo[i]=Foo(4+i);
        }
    }
};

In the schema you have in your question, child1 or child2 can appear in any order, any number of times. So this sounds like what you are looking for.

Edit: if you wanted only one of them to appear an unlimited number of times, the unbounded would have to go on the elements instead:

Edit: Fixed type in XML.

Edit: Capitalised O in maxOccurs

<xs:element name="foo">
   <xs:complexType>
     <xs:choice maxOccurs="unbounded">
       <xs:element name="child1" type="xs:int" maxOccurs="unbounded"/>
       <xs:element name="child2" type="xs:string" maxOccurs="unbounded"/>
     </xs:choice>
   </xs:complexType>
</xs:element>

This is not possible, as you say, from a security stand point. The only way you could simulate it, is by creating a modeless dialog window.

There are many third-party javascript-plugins that you could use to fake this effect so you do not have to write all that code.

An <input>'s width is generated from its size attribute. The default size is what's driving the auto width.

You could try width:100% as illustrated in my example below.

Doesn't fill width:

<form action='' method='post' style='width:200px;background:khaki'>
  <input style='width:auto' />
</form>

Fills width:

<form action='' method='post' style='width:200px;background:khaki'>
  <input style='width:100%' />
</form>

Smaller size, smaller width:

<form action='' method='post' style='width:200px;background:khaki'>
  <input size='5' />
</form>

UPDATE

Here's the best I could do after a few minutes. It's 1px off in FF, Chrome, and Safari, and perfect in IE. (The problem is #^&* IE applies borders differently than everyone else so it's not consistent.)

<div style='padding:30px;width:200px;background:red'>
  <form action='' method='post' style='width:200px;background:blue;padding:3px'>
    <input size='' style='width:100%;margin:-3px;border:2px inset #eee' />
    <br /><br />
    <input size='' style='width:100%' />
  </form>
</div>

You can groupby on cols 'A' and 'B' and call size and then reset_index and rename the generated column:

In [26]:

df1.groupby(['A','B']).size().reset_index().rename(columns={0:'count'})
Out[26]:
     A    B  count
0   no   no      1
1   no  yes      2
2  yes   no      4
3  yes  yes      3

update

A little explanation, by grouping on the 2 columns, this groups rows where A and B values are the same, we call size which returns the number of unique groups:

In[202]:
df1.groupby(['A','B']).size()

Out[202]: 
A    B  
no   no     1
     yes    2
yes  no     4
     yes    3
dtype: int64

So now to restore the grouped columns, we call reset_index:

In[203]:
df1.groupby(['A','B']).size().reset_index()

Out[203]: 
     A    B  0
0   no   no  1
1   no  yes  2
2  yes   no  4
3  yes  yes  3

This restores the indices but the size aggregation is turned into a generated column 0, so we have to rename this:

In[204]:
df1.groupby(['A','B']).size().reset_index().rename(columns={0:'count'})

Out[204]: 
     A    B  count
0   no   no      1
1   no  yes      2
2  yes   no      4
3  yes  yes      3

groupby does accept the arg as_index which we could have set to False so it doesn't make the grouped columns the index, but this generates a series and you'd still have to restore the indices and so on....:

In[205]:
df1.groupby(['A','B'], as_index=False).size()

Out[205]: 
A    B  
no   no     1
     yes    2
yes  no     4
     yes    3
dtype: int64

As far as I know PKCS#12 is just a certificate/public/private key store. If you extracted a public key from PKCS#12 file, OpenSSH should be able to use it as long as it was extracted in PEM format. You probably already know that you also need a corresponding private key (also in PEM) in order to use it for ssh-public-key authentication.

Try this first:

git checkout master

(If you're on a different branch than master, use the branch name there instead.)

If that doesn't work, try...

For a single file:

git checkout HEAD /path/to/file

For the entire repository working copy:

git reset --hard HEAD

And if that doesn't work, then you can look in the reflog to find your old head SHA and reset to that:

git reflog
git reset --hard <sha from reflog>

HEAD is a name that always points to the latest commit in your current branch.

There's more than one way to skin this problem so here's my solution:

1. Use Select() to convert the key-value pair to a string;
2. Convert to a list of strings;
3. Write out to the console using ForEach().

dict.Select(i => $"{i.Key}: {i.Value}").ToList().ForEach(Console.WriteLine);

There is also another easy way to check the latest version without going to NPM if you are using VS Code.

In package.json file check for the module you want to know the latest version. Remove the current version already present there and do CTRL + space or CMD + space(mac).The VS code will show the latest versions

Try using a single quote instead of double quotes along with -g

Following scenario worked for me

curl -g -d '{"collection":[{"NumberOfParcels":1,"Weight":1,"Length":1,"Width":1,"Height":1}]}" -H "Accept: application/json" -H "Content-Type: application/json" --user [email protected]:123456 -X POST  https://yoururl.com

WITH

curl -g -d "{'collection':[{'NumberOfParcels':1,'Weight':1,'Length':1,'Width':1,'Height':1}]}" -H "Accept: application/json" -H "Content-Type: application/json" --user [email protected]:123456 -X POST  https://yoururl.com

This especially resolved my error curl command error : bad url colon is first character

Currently, Firefox honors the language of the HTML element in which the input resides. For example, try this fiddle in Firefox:

http://jsfiddle.net/ashraf_sabry_m/yzzhop75/1/

You will see that the numerals are in Arabic, and the comma is used as the decimal separator, which is the case with Arabic. This is because the BODY tag is given the attribute lang="ar-EG".

Next, try this one:

http://jsfiddle.net/ashraf_sabry_m/yzzhop75/2/

This one is displayed with a dot as the decimal separator because the input is wrapped in a DIV given the attribute lang="en-US".

So, a solution you may resort to is to wrap your numeric inputs with a container element that is set to use a culture that uses dots as the decimal separator.

I had the same problem with python3 and pip3. Decision: solving all conflicts with links and other stuff when do

brew doctor

After that

brew reinstall python3

You do

for (Thread t : new Thread[] { th1, th2, th3, th4, th5 })
    t.join()

After this for loop, you can be sure all threads have finished their jobs.

Here you go: ES5

var test = 'Hello World';
if( test.indexOf('World') >= 0){
  // Found world
}

With ES6 best way would be to use includes function to test if the string contains the looking work.

const test = 'Hello World';
if (test.includes('World')) { 
  // Found world
}

Using onBackPressed() method:

@Override
public void onBackPressed() {    
    android.os.Process.killProcess(android.os.Process.myPid());
}

or use the finish() method, I have something like

//Password Error, I call function
    Quit();             


    protected void Quit() {
        super.finish();
    }

With super.finish() you close the super class's activity.

That's not possible using the built-in Array.prototype.map. However, you could use a simple for-loop instead, if you do not intend to map any values:

var hasValueLessThanTen = false;
for (var i = 0; i < myArray.length; i++) {
  if (myArray[i] < 10) {
    hasValueLessThanTen = true;
    break;
  }
}

Or, as suggested by @RobW, use Array.prototype.some to test if there exists at least one element that is less than 10. It will stop looping when some element that matches your function is found:

var hasValueLessThanTen = myArray.some(function (val) { 
  return val < 10;
});

Why are these new categories needed? Are the WG21 gods just trying to confuse us mere mortals?

I don't feel that the other answers (good though many of them are) really capture the answer to this particular question. Yes, these categories and such exist to allow move semantics, but the complexity exists for one reason. This is the one inviolate rule of moving stuff in C++11:

Thou shalt move only when it is unquestionably safe to do so.

That is why these categories exist: to be able to talk about values where it is safe to move from them, and to talk about values where it is not.

In the earliest version of r-value references, movement happened easily. Too easily. Easily enough that there was a lot of potential for implicitly moving things when the user didn't really mean to.

Here are the circumstances under which it is safe to move something:

1. When it's a temporary or subobject thereof. (prvalue)
2. When the user has explicitly said to move it.

If you do this:

SomeType &&Func() { ... }

SomeType &&val = Func();
SomeType otherVal{val};

What does this do? In older versions of the spec, before the 5 values came in, this would provoke a move. Of course it does. You passed an rvalue reference to the constructor, and thus it binds to the constructor that takes an rvalue reference. That's obvious.

There's just one problem with this; you didn't ask to move it. Oh, you might say that the && should have been a clue, but that doesn't change the fact that it broke the rule. val isn't a temporary because temporaries don't have names. You may have extended the lifetime of the temporary, but that means it isn't temporary; it's just like any other stack variable.

If it's not a temporary, and you didn't ask to move it, then moving is wrong.

The obvious solution is to make val an lvalue. This means that you can't move from it. OK, fine; it's named, so its an lvalue.

Once you do that, you can no longer say that SomeType&& means the same thing everwhere. You've now made a distinction between named rvalue references and unnamed rvalue references. Well, named rvalue references are lvalues; that was our solution above. So what do we call unnamed rvalue references (the return value from Func above)?

It's not an lvalue, because you can't move from an lvalue. And we need to be able to move by returning a &&; how else could you explicitly say to move something? That is what std::move returns, after all. It's not an rvalue (old-style), because it can be on the left side of an equation (things are actually a bit more complicated, see this question and the comments below). It is neither an lvalue nor an rvalue; it's a new kind of thing.

What we have is a value that you can treat as an lvalue, except that it is implicitly moveable from. We call it an xvalue.

Note that xvalues are what makes us gain the other two categories of values:

• A prvalue is really just the new name for the previous type of rvalue, i.e. they're the rvalues that aren't xvalues.

• Glvalues are the union of xvalues and lvalues in one group, because they do share a lot of properties in common.

So really, it all comes down to xvalues and the need to restrict movement to exactly and only certain places. Those places are defined by the rvalue category; prvalues are the implicit moves, and xvalues are the explicit moves (std::move returns an xvalue).

Set the XML as:

<ToggleButton
    android:id="@+id/flashlightButton"
    style="@style/Button"
    android:layout_above="@+id/buttonStrobeLight"
    android:layout_marginBottom="20dp"
    android:onClick="onToggleClicked"
    android:text="ToggleButton"
    android:textOn="Light ON"
    android:textOff="Light OFF" />

I may be slightly off-topic as you did mention the need for a username and password, and my understanding of the issue is admitedly not the best but is OpenID something worth considering?

If you use OpenID then you don't end up storing any credentials at all if I understand the technology correctly and users can use credentials that they already have, avoiding the need to create a new identity that is specific to your application.

It may not be suitable if the application in question is purely for internal use though

RPX provides a nice easy way to intergrate OpenID support into an application.

to check whether the sudo package is installed on your system, type sudo , and press Enter . If you have sudo installed the system will display a short help message, otherwise you will see something like sudo: command not found

To install sudo, run one of the following commands using root account:

apt-get install sudo # If your system based on apt package manager

yum install sudo # If your system based on yum package manager

For any tag one can select all text inside that tag by this short and simple code. It will highlight the entire tag area with yellow colour and select text inside it on single click.

document.onclick = function(event) {
    var range, selection;
event.target.style.backgroundColor = 'yellow';
        selection = window.getSelection();
        range = document.createRange();
        range.selectNodeContents(event.target);
        selection.removeAllRanges();
        selection.addRange(range);
};

position: fixed; will also "pop" an element out of the flow, as you say. :)

position: absolute must be accompanied by a position. e.g. top: 1rem; left: 1rem

position: fixed however, will place the element where it would normally appear according to the document flow, but prevent it from moving after that. It also effectively set's the height to 0px (with regards to the dom) so that the next element shifts up over it.

This can be pretty cool, because you can set position: fixed; z-index: 1 (or whatever z-index you need) so that it "pops" over the next element.

This is especially useful for fixed position headers that stay at the top when you scroll, for example.

This was done using Toad for Oracle 12.8.0.49

ALTER TABLE SCHEMA.TABLENAME 
    MODIFY (COLUMNNAME NEWDATATYPE(LENGTH)) ;

For example,

ALTER TABLE PAYROLL.EMPLOYEES 
    MODIFY (JOBTITLE VARCHAR2(12)) ;

.live() was deprecated and has now been removed from jQuery 1.9 You should use .on()

One option would be to put all the code in the loop inside a Sub and then just return from that Sub when you want to "continue".

Not perfect, but I think it would be less confusing that the extra loop.

[a-zA-Z] should do that just fine.

You can reference the cheat sheet.

perl -lanse 'print $F[$j-1] if $. == $i' -- -i=5 -j=3 file

Perl equivalents of @Hai's solutions:

if you are looking for second columns that contains abc:

perl -lane 'print if $F[1] =~ /abc/' foo

... and if you want to print only a particular column:

perl -lane 'print $F[2] if $F[1] =~ /abc/' foo

... and for a particular line number:

perl -lane 'print $F[2] if $F[1] =~ /abc/ && $. == 5' foo

-l removes newlines, and adds them back in when printing
-a autosplits the input line into array @F, using whitespace as the delimiter
-n loop over each line of the input file
-e execute the code within quotes
$F[1] is the second element of the array, since Perl starts at 0
$. is the line number

I would suggest the P: drive is not mapped for the account that sql server has started as.

. is a shorthand for the current directory and is used in Linux and Unix to execute a compiled program in the current directory. That is why you don't see this used in Web Development much except by open source, non-Windows frameworks like Google Angular which was written by people stuck on open source platforms.

./ also resolves to the current directory and is atypical in Web but supported as a path in some open source frameworks. Because it resolves the same as no path to the current file directory its not used. Example: ./image.jpg = image.jpg. Again, this is a relic of Unix operating systems that need path resolutions like this to run executables and resolve paths for security reasons. Its not a typical web path. That is why this syntax is redundant.

../ is a traditional web path that goes one directory up

/ is the ROOT of your website

These path resolutions below are true...

./folder= folder this is always true in web path resolution

./file.html = file.html this is always true in web path resolution

./ = {no path} an empty path is the same as ./ in the web world

{no path} = / an empty path is the same as the web root if your file is in the root directory

./ = / ONLY if you are in the root folder

../ = / ONLY if you are one folder below the web root

Microsoft listed the following methods for getting the a View definition: http://technet.microsoft.com/en-us/library/ms175067.aspx

USE AdventureWorks2012;
GO
SELECT definition, uses_ansi_nulls, uses_quoted_identifier, is_schema_bound
FROM sys.sql_modules
WHERE object_id = OBJECT_ID('HumanResources.vEmployee'); 
GO

USE AdventureWorks2012; 
GO
SELECT OBJECT_DEFINITION (OBJECT_ID('HumanResources.vEmployee')) 
AS ObjectDefinition; 
GO

EXEC sp_helptext 'HumanResources.vEmployee';

Yes, that will work as you expect it to. Unfortunately, I seem to be having trouble to find an explicit statement of this in the MySQL manual.

Foreign keys mean the value must exist in the other table. NULL refers to the absence of value, so when you set a column to NULL, it wouldn't make sense to try to enforce constraints on that.

A/code.cpp

#include <B/file.hpp>

A/a/code2.cpp

#include <B/file.hpp>

Compile using:

g++ -I /your/source/root /your/source/root/A/code.cpp
g++ -I /your/source/root /your/source/root/A/a/code2.cpp

Edit:

You can use environment variables to change the path g++ looks for header files. From man page:

Some additional environments variables affect the behavior of the preprocessor.

   CPATH
   C_INCLUDE_PATH
   CPLUS_INCLUDE_PATH
   OBJC_INCLUDE_PATH

Each variable's value is a list of directories separated by a special character, much like PATH, in which to look for header files. The special character, "PATH_SEPARATOR", is target-dependent and determined at GCC build time. For Microsoft Windows-based targets it is a semicolon, and for almost all other targets it is a colon.

CPATH specifies a list of directories to be searched as if specified with -I, but after any paths given with -I options on the command line. This environment variable is used regardless of which language is being preprocessed.

The remaining environment variables apply only when preprocessing the particular language indicated. Each specifies a list of directories to be searched as if specified with -isystem, but after any paths given with -isystem options on the command line.

In all these variables, an empty element instructs the compiler to search its current working directory. Empty elements can appear at the beginning or end of a path. For instance, if the value of CPATH is ":/special/include", that has the same effect as -I. -I/special/include.

There are many ways you can change an environment variable. On bash prompt you can do this:

$ export CPATH=/your/source/root
$ g++ /your/source/root/A/code.cpp
$ g++ /your/source/root/A/a/code2.cpp

You can of course add this in your Makefile etc.

this is how I do it

function run_ajax(obj) {
    $.ajax({
        type:"POST",
        url: prefix,
        data: obj.pdata,
        dataType: 'json',
        error: function(data) {
            //do error stuff
        },
        success: function(data) {

            if(obj.func){
                obj.func(data); 
            }

        }
    });
}

alert_func(data){
    //do what you want with data
}

var obj= {};
obj.pdata = {sumbit:"somevalue"}; // post variable data
obj.func = alert_func;
run_ajax(obj);

yet another solution uses tr:

echo $testVar | tr -d '\r'
cat myscript | tr -d '\r'

the option -d stands for delete.

    public table2() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 485, 218);
    setTitle("jtable");
    getContentPane().setLayout(null);

    String data[][] = { { "Row1/1", "Row1/2", "Row1/3" },
            { "Row2/1", "Row2/2", "Row2/3" },
            { "Row3/1", "Row3/2", "Row3/3" },
            { "Row4/1", "Row4/2", "Row4/3" }, };

    String header[] = { "Column 1", "Column 2", "Column 3" };

    // Table
    JTable table = new JTable(data,header);


    // ScrollPane
    JScrollPane scrollPane = new JScrollPane(table);
    scrollPane.setBounds(36, 37, 407, 79);
    getContentPane().add(scrollPane);

   }

}

To do it without VS2010 installation, and only 2012, set the msvs_version flag:

node-gyp rebuild --msvs_version=2012

npm install <module> --msvs_version=2012

as per @Jacob comment

npm install --msvs_version=2013 if you have the 2013 version

With the Netbeans 10, commenting out the netbeans_jdkhome setting in .../etc/netbeans.conf doesn't do the job anymore. It is necessary to specify the right directory depending of 32/64 bitness.

E.g. for 64 bit application: netbeans_jdkhome="C:\Program Files\AdoptOpenJDK\jdk8u202-b08"

.table-striped > tbody > tr:nth-child(2n+1) > td, .table-striped > tbody > tr:nth-child(2n+1) > th {
   background-color: red;
}

change this line in bootstrap.css or you could use (odd) or (even) instead of (2n+1)

Edited to reflect update to question

$(document).ready(function() {
    $(".res a").click(function() {
        alert($(this).attr("href"));
    });
});

The directive can access any attribute that is defined on the same element, even if the directive itself is not the element.

Template:

<div example-directive example-number="99" example-function="exampleCallback()"></div>

Directive:

app.directive('exampleDirective ', function () {
    return {
        restrict: 'A',   // 'A' is the default, so you could remove this line
        scope: {
            callback : '&exampleFunction',
        },
        link: function (scope, element, attrs) {
            var num = scope.$eval(attrs.exampleNumber);
            console.log('number=',num);
            scope.callback();  // calls exampleCallback()
        }
    };
});

fiddle

If the value of attribute example-number will be hard-coded, I suggest using $eval once, and storing the value. Variable num will have the correct type (a number).

You can't upload files via ajax, you need to use an iFrame or some other trickery to do a full postback. This is mainly due to security concerns.

Here's a decent write-up including a sample project using SWFUpload and ASP.Net MVC by Steve Sanderson. It's the first thing I read getting this working properly with Asp.Net MVC (I was new to MVC at the time as well), hopefully it's as helpful for you.

The .size() function is available in Jquery and many other libraries.

The .length property works only when the index is an integer.

The length property will work with this type of array:

var nums = new Array();
nums[0] = 1; 
nums[1] = 2;
print(nums.length); // displays 2

The length property won't work with this type of array:

var pbook = new Array(); 
pbook["David"] = 1; 
pbook["Jennifer"] = 2;
print(pbook.length); // displays 0

So in your case you should be using the .length property.

Simplest is when you want to make a integer a string do

var a,b, c;
a = 1;
b = a.toString(); // This will give you string

Now, from the variable b which is of type string we can get the integer

c = b *1; //This will give you integer value of number :-)

If you want to check above is a number. If you are not sure if b contains integer then you can use

if(isNaN(c*1)) {
  //NOt a number
}
else //number

Jérôme Petazzoni has a pretty interesting blog post on how to Attach a volume to a container while it is running. This isn't something that's built into Docker out of the box, but possible to accomplish.

As he also points out

This will not work on filesystems which are not based on block devices.

It will only work if /proc/mounts correctly lists the block device node (which, as we saw above, is not necessarily true).

Also, I only tested this on my local environment; I didn’t even try on a cloud instance or anything like that

YMMV

If you are using Spring Framework with application.yml and having trouble to make the test find the SQL file on the INIT property, you can use the classpath: notation.

For example, if you have a init.sql SQL file on the src/test/resources, just use:

url=jdbc:h2:~/test;INIT=RUNSCRIPT FROM 'classpath:init.sql';DB_CLOSE_DELAY=-1;

The recommendation is was to start their name with "X-". E.g. X-Forwarded-For, X-Requested-With. This is also mentioned in a.o. section 5 of RFC 2047.

Update 1: On June 2011, the first IETF draft was posted to deprecate the recommendation of using the "X-" prefix for non-standard headers. The reason is that when non-standard headers prefixed with "X-" become standard, removing the "X-" prefix breaks backwards compatibility, forcing application protocols to support both names (E.g, x-gzip & gzip are now equivalent). So, the official recommendation is to just name them sensibly without the "X-" prefix.

Update 2: On June 2012, the deprecation of recommendation to use the "X-" prefix has become official as RFC 6648. Below are cites of relevance:

3. Recommendations for Creators of New Parameters

...

3. SHOULD NOT prefix their parameter names with "X-" or similar constructs.

4. Recommendations for Protocol Designers

...

4. SHOULD NOT prohibit parameters with an "X-" prefix or similar constructs from being registered.

5. MUST NOT stipulate that a parameter with an "X-" prefix or similar constructs needs to be understood as unstandardized.

6. MUST NOT stipulate that a parameter without an "X-" prefix or similar constructs needs to be understood as standardized.

Note that "SHOULD NOT" ("discouraged") is not the same as "MUST NOT" ("forbidden"), see also RFC 2119 for another spec on those keywords. In other words, you can keep using "X-" prefixed headers, but it's not officially recommended anymore and you may definitely not document them as if they are public standard.

Summary:

• the official recommendation is to just name them sensibly without the "X-" prefix
• you can keep using "X-" prefixed headers, but it's not officially recommended anymore and you may definitely not document them as if they are public standard

this is the correct answer

$('#theid').css('display') == 'none'

You can also use following line to find if it is display block or none

$('.deal_details').is(':visible')

In Vim, use :insert. This will keep all your formatting and not do autoindenting. For more information help :insert.

There's not a good way to convert it to foreach, because mysql_fetch_array() just fetches the next result from $result_select. If you really wanted to foreach, you could do pull all the results into an array first, doing something like the following:

$result_list = array();
while($row = mysql_fetch_array($result_select)) {
   result_list[] = $row;
}

foreach($result_list as $row) {
   ...
}

But there's no good reason I can see to do that - and you still have to use the while loop, which is unavoidable due to how mysql_fetch_array() works. Why is it so important to use a foreach()?

EDIT: If this is just for learning purposes: you can't convert this to a foreach. You have to have a pre-existing array to use a foreach() instead of a while(), and mysql_fetch_array() fetches one result per call - there's no pre-existing array for foreach() to iterate through.

I made this for my simple text editor.

Differences from other methods:

• High performance
• Works with all spaces

usage

// get current selection
const [start, end] = getSelectionOffset(container)

// change container html
container.innerHTML = newHtml

// restore selection
setSelectionOffset(container, start, end)

// use this instead innerText for get text with keep all spaces
const innerText = getInnerText(container)
const textBeforeCaret = innerText.substring(0, start)
const textAfterCaret = innerText.substring(start)

You need to install tkinter for python3.

On Fedora pip3 install tkinter --user returns Could not find a version that satisfies the requirement... so I have to command: dnf install python3-tkinter. This have solved my problem

I was looking to do this myself, and I wasnt satisfied with any of the answers provided simply because, I believe, they are quadratic time, and I need to do this on lists hundreds of items long.

I ended up extending jquery, and my solution uses jquery, but could easily be modified to use straight javascript.

I only access each item twice, and perform one linearithmic sort, so this should, I think, work out to be a lot faster on large datasets, though I freely confess I could be mistaken there:

sortList: function() {
   if (!this.is("ul") || !this.length)
      return
   else {
      var getData = function(ul) {
         var lis     = ul.find('li'),
             liData  = {
               liTexts : []
            }; 

         for(var i = 0; i<lis.length; i++){
             var key              = $(lis[i]).text().trim().toLowerCase().replace(/\s/g, ""),
             attrs                = lis[i].attributes;
             liData[key]          = {},
             liData[key]['attrs'] = {},
             liData[key]['html']  = $(lis[i]).html();

             liData.liTexts.push(key);

             for (var j = 0; j < attrs.length; j++) {
                liData[key]['attrs'][attrs[j].nodeName] = attrs[j].nodeValue;
             }
          }

          return liData;
       },

       processData = function (obj){
          var sortedTexts = obj.liTexts.sort(),
              htmlStr     = '';

          for(var i = 0; i < sortedTexts.length; i++){
             var attrsStr   = '',
                 attributes = obj[sortedTexts[i]].attrs;

             for(attr in attributes){
                var str = attr + "=\'" + attributes[attr] + "\' ";
                attrsStr += str;
             }

             htmlStr += "<li "+ attrsStr + ">" + obj[sortedTexts[i]].html+"</li>";
          }

          return htmlStr;

I guess you must be connecting to cloud.mongodb.com to your cluster.

One quick fix is to go to the connection tab and add your current IP address(in the cluster portal of browser or desktop app). The IP address must have changed due to a variety of reasons, such as changing the wifi.

None of the answers seemed to work for me or were too complicated. Luckily, it's not complicated with xargs (Tested on Ubuntu 20.04).

This works with each arg on a separate line in the file as the OP mentions and was what I needed as well.

cat foo.txt | xargs my_command

One thing to note is that it doesn't seem to work with aliased commands.

The accepted answer works if the command accepts multiple args wrapped in a string. In my case using (Neo)Vim it does not and the args are all stuck together.

xargs does it probably and actually gives you separate arguments supplied to the command.

In Kotlin:

val callback = requireActivity().onBackPressedDispatcher.addCallback(this) {
    // Handle the back button event
}

For more information you can check this.

There is also specific question about overriding back button in Kotlin.

You will have to specify a fixed height, you cannot use 100% because there is nothing for this to be compared to, as in height=100% of what?

If you get this issue, then either

• the formControlName is not located on the value accessor element.
• or you're not importing the module for that element.

Oddly enough, the issue for me was I was trying to open 2012 SQL Server Integration Services on SSMS 2008 R2. When I opened the same in SSMS 2012, it connected right away.

In 2017, the thing closest to Javadoc would probably DocFx which was developed by Microsoft and comes as a Commmand-Line-Tool as well as a VS2017 plugin.

It's still a little rough around the edges but it looks promising.

Another alternative would be Wyam which has a documentation recipe suitable for net aplications. Look at the cake documentation for an example.

You don't need to go level up and use .. since all buttons are on the same level:

//button[contains(.,'Arcade Reader')]/preceding-sibling::button[@name='settings']

In C, you can use the built in qsort command:

int compare( const void* a, const void* b)
{
     int int_a = * ( (int*) a );
     int int_b = * ( (int*) b );

     if ( int_a == int_b ) return 0;
     else if ( int_a < int_b ) return -1;
     else return 1;
}

qsort( a, 6, sizeof(int), compare )

see: http://www.cplusplus.com/reference/clibrary/cstdlib/qsort/

To answer the second part of your question: an optimal (comparison based) sorting algorithm is one that runs with O(n log(n)) comparisons. There are several that have this property (including quick sort, merge sort, heap sort, etc.), but which one to use depends on your use case.

As a side note, you can sometime do better than O(n log(n)) if you know something about your data - see the wikipedia article on Radix Sort

git update-index should do what you want

This will tell git you want to start ignoring the changes to the file
git update-index --assume-unchanged path/to/file

When you want to start keeping track again
git update-index --no-assume-unchanged path/to/file

Having done some more digging, I think my issue is something to do with the type of library I am building gtest into. When building gtest with CMake, if BUILD_SHARED_LIBS is un-checked, and I link my program against these .lib files I get the errors mentioned above. However, if BUILD_SHARED_LIBS is checked then I produce a set of .lib and .dll files. When now linking against these .lib files the program compiles, but when run complains that it can't find gtest.dll.

That is because you have to add -DGTEST_LINKED_AS_SHARED_LIBRARY=1 to compiler definitions in your project if you want to use gtest as a shared library.

You could also use the static libraries, provided you compiled it with gtest_force_shared_crt option on to eliminate errors you have seen.

I like the library but adding it to the project is a real pain. And you have no chance to do it right unless you dig (and hack) into the gtest cmake files. Shame. In particular I do not like the idea of adding gtest as a source. :)

A function name can become a variable name (and thus be passed as an argument) by dropping the parentheses. A variable name can become a function name by adding the parentheses.

In your example, equate the variable rules to one of your functions, leaving off the parentheses and the mention of the argument. Then in your game() function, invoke rules( v ) with the parentheses and the v parameter.

if puzzle == type1:
    rules = Rule1
else:
    rules = Rule2

def Game(listA, listB, rules):
    if rules( v ) == True:
        do...
    else:
        do...

From your local machine:

rsync -chavzP --stats [email protected]:/path/to/copy /path/to/local/storage

From your local machine with a non standard ssh port:

rsync -chavzP -e "ssh -p $portNumber" [email protected]:/path/to/copy /local/path

Or from the remote host, assuming you really want to work this way and your local machine is listening on SSH:

rsync -chavzP --stats /path/to/copy [email protected]:/path/to/local/storage

See man rsync for an explanation of my usual switches.

To add a header just add the following code to the location block where you want to add the header:

location some-location {
  add_header X-my-header my-header-content;      
}

Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.

if you have array of object and you would like to deserialize them in compoent

get example() { this.arrayOfObject.map(i => JSON.stringify (i) ) };

then in template

<ul>
   <li *ngFor="obj of example">{{obj}}</li>
</ul>

Use <packages xmlns="urn:packages">in the place of <packages>

What you want is maxlength.

Valid for text, search, url, tel, email, and password, it defines the maximum number of characters (as UTF-16 code units) the user can enter into the field. This must be an integer value 0 or higher. If no maxlength is specified, or an invalid value is specified, the field has no maximum length. This value must also be greater than or equal to the value of minlength.

You might consider using one of these input types.

To install any other package I have to use the latest version of pip, since the 9.0.1 has this SSL problem. To upgrade the pip by pip itself, I have to solve this SSL problem first. To jump out of this endless loop, I find this only way that works for me.

1. Find the latest version of pip in this page: https://pypi.org/simple/pip/
2. Download the .whl file of the latest version.
3. Use pip to install the latest pip. (Use your own latest version here)

sudo pip install pip-10.0.1-py2.py3-none-any.whl

Now the pip is the latest version and can install anything.

As all the other answers show, the problem is that adding a std::string and a const char* using + results in a std::string, while system() expects a const char*. And the solution is to use c_str(). However, you can also do it without a temporary:

string name = "john";
system((" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'").c_str());

In short, The basic problem an interface is trying to solve is to separate how we use something from how it is implemented. But you should consider interface is not a contract. Read more here.

There are two ways to go about doing this.

1. Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.

2. handleClick: function() { alert(this.refs.myInput.value); },

I used

diff -rqyl folder1 folder2 --exclude=node_modules

in my nodejs apps.

There's a JS QrCode scanner, that works on mobile sites with a camera:

I have worked with it for one of my project and it works pretty good !

2017 Update I guess. textarea worked fine for me using Spring, Bootstrap and a bunch of other things. Got the SOAP payload stored in a DB, read by Spring and push via Spring-MVC. xmp didn't work at all.

You can try following sample http://jsfiddle.net/xKJB8/3/

<img id="preview" src="http://www.gravatar.com/avatar/0e39d18b89822d1d9871e0d1bc839d06?s=128&d=identicon&r=PG">
<canvas id="myCanvas" />

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
var img = document.getElementById("preview");
ctx.drawImage(img, 10, 10);
alert(c.toDataURL());

You can try this:

s = r'long\annoying\path'

If selection is not important, it is better to use an ItemsControl wrapped in a ScrollViewer. This combination is more light-weight than the Listbox (which actually is derived from ItemsControl already) and using it would eliminate the need to use a cheap hack to override behavior that is already absent from the ItemsControl.

In cases where the selection behavior IS actually important, then this obviously will not work. However, if you want to change the color of the Selected Item Background in such a way that it is not visible to the user, then that would only serve to confuse them. In cases where your intention is to change some other characteristic to indicate that the item is selected, then some of the other answers to this question may still be more relevant.

Here is a skeleton of how the markup should look:

    <ScrollViewer>
        <ItemsControl>
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    ...
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </ScrollViewer>
